Thread: where and how is n_long defined

I see a struct in ip.h:

Code:

struct   ip_timestamp {                                               
    u_char    ipt_code;      /* IPOPT_TS */                           
    u_char    ipt_len;       /* size of structure (variable) */       
    u_char    ipt_ptr;       /* index of current entry */             
    u_int     ipt_flg:4,          /* flags, see below */              
         ipt_oflw:4;         /* overflow counter */                   
    union {                                                           
         n_long    ipt_time[1];                                       
         struct    ipt_ta {                                           
              struct in_addr ipt_addr;                                
              n_long ipt_time;                                        
         } ipt_ta[1];                                                 
    } ipt_union;                                                      
};

does anybody know where is n_long defined?
Thank you
